1 Claim.

This invention relates to methods of constructing walls, and isparticularly well adapted, altho not limited to use in the constructionof the outside walls of buildings.

The present application is a division of an application filed by meDecember 5, 1942, Serial No. 467,971, disclosing Molding Apparatus forforming Buildings, which has since matured in Patent No. 2,434,708, onJanuary 20, 1948.

The principal object of the invention is to provide a method ofconstructing buildings whereby the hollow walls, with both vertical andhorizontal air spaces, may be progressively formed with footingsupwardly of an integral mass of concrete or like cementitous material,the vertical spaces being in communication with horizontal spaces formedby tubes of any suitable material as metal, clay or composition ofsufficient strength to sustain the superimposed load of concrete or Vthelike, until it has set. These tubes are preferably disposed in theirdesired positions before the concrete sets and arranged in verticallyspaced relation with concrete surrounding the circumference of eachtube, held against lateral displacement by suitable forms andcollapsible cores, which may be progressively placed as the wall isbuilt to the desired height.

Other objects and advantages of the invention will appear in thefollowing detailed description, taken drawings, forming a part of thisspecification, and in which drawings:

Fig. 1 is a vertical cross sectional view thru, a suitable footingproviding with suitable anchor members or bolts, reinforcement anchorsand guide stubs extending upwardly from the top thereof.

Fig, 2 is a view partly in plan, showing the footing on a reduced scale,and partly in horizontal section thru suitable molding apparatus whichmay be used in practicing this method, the tubes for horizontal airspaces also being shown in plan.

Fig. 3 is a vertical, cross sectional view thru the footing and showingthe tubes and collapsible 'cores in elevation, together with suitablemeans for supporting theA tubes, .a portion of the view being brokenaway to condensethe same.

Fig. 4, is a side elevation of the wall form, a portion being brokenaway to condense the view.

Fig. 5 is a fragmentary, vertical, cross sectional view similar to thelower vportion of Fig. 3, but showing concrete in place between the wallform and surrounding the tubes.

Fig. 6 is a fragmentary, horizontal sectional in connection with theaccompanying view of a finished wall portion and showing a vertical voidand communicating horizontal voids. Fig. 7 is a vertical, longitudinalsectional view thru the wall at the vertical voids and axes of thetubes, a portion of the view being broken away to condense the view.

The preferred rst step in the method is to provide a footing 60 ofconcrete having embedded therein suitably spaced form anchor members 18,such as bolts; reinforcement anchors 8|); and, guide stubs 8|, whichextend upwardly from the top surface of the footing as shown in Fig. l.The form anchor members i3 are spaced apart one from anotherlongitudinally of the footing along lines adjacent its inner and outersides so as to detachably secure spaced wall material confining forms tothe footing as shown in Fig. 2. These forms may comprise spaced verticalchannel members |3|, and metallic flanged mold panels |35, of thecharacter shown in my aforesaid Patent 2,434,708, it sufcing to statethat, in the example shown the bolts extend thru foot anges 8 of thechannel members ISI, and bottom anges 9 of the'lowermost panels |35, andreceive nuts l0 to hold these forms in place.

Likewise the guide stubs 8| are disposed 'in groups spaced apart onefrom another longitudinally of the footing Ell, each group comprising aplurality of stubs in lines inwardly of the lines of fo-rm anchormembers 13, so as to hold suitable, vertically disposed core forms 83against lateral displacement, between the form members |3| and |35, asshown in Figs. 2 and 3. These core forms 83 are preferably of thecollapsible type an example of which is shown in my covpendingapplication for patent on collapsible Ywall forms and cores. In theexample shown the Vapparatus 99 comprises a plurality of verticallyspaced rods 274, arranged in pairs, a plurality oi' tubes 215 arrangedbetween the rods of each pair, and means 216 engaging the rods and tubesfor securing the latter in the vdesired position against displacement ascementitious material is poured into the cavity between the wall formsand about the collapsible cores, reinforcing rods and tubes.

Suitable ties 211 of wire or the like may be used to secure the lowerportions of the rods 21d to the reinforcement anchors 89, and a suitablesteadying bar 218 is also disclosed in Fig. 3 to temporarily hold therods at their upper ends against displacement.

The rods 214 may be of any suitable cross section with one rod of eachpair adjacent to and spaced from one of the upright wall forms, and theother adjacent to and spaced from the other upright wall form as shownin Figure 2. The tie 211 may lbe wire wrapped around the lower end ofthe rod and its adjacent reinforcement anchor 80. The upper ends of therods may extend thru holes 219 in the bar 218, which is temporarilysecured to one of the wall forms as by bolt 239.

The tubes 215 may be of any suitable, inexpensive material capable ofwithstanding the pressure of the superimposed load of concrete, until ithas become set. It is preferred to use tubes which may be cut fromtubular stocks, with a saw, or other suitable instrument, to the desiredlength and, to have the open ends of th-e tubes in planes perpendicularto the axes of the tubes. However, these tubes may be of moldedmaterial, such as clay, of the desired length, or of sheet metal formedinto tubes. tubes abut against the collapsible core forms 83 as shown inFig. 2 so they are temporarily closed against ingress of cementitiousmaterial while the wall is being poured and until the collapsible coreforms are removed.

The means 216 may comprise wires arranged crosswise of the reinforcingrods, above and below the tubes 215 and having their end portions 281wrapped around the reinforcing rods, but this is merely by way ofexample, since any suitable means may be provided for this purpose.

In carrying out the method, the footing Bil iS formed with the anchormembers or fbolts 13, the reinforcement anchors 89 and the guide stubs8l in place, In locating these projecting elements 13, 85 and Si care isexercised so as to have the longitudinal rows of anchor members 5Sspaced apart the correct distance so that when the -V spaced wallmaterial confining forms |31 and |35 are placed, a wall of the desiredthickness may be produced. The guide stubs Si arealso accurately locatedso that they may removably retain the core forms in proper position,which may be arranged either in engaging pairs or isolated in spacedapart relation one to another, as shown in Fig. .2. The reinforcementanchors need not be so accurately located as to distance between thecore forms, but should be spaced the desired distance from the wallforms E31 and 135 so as to locate the tub-es .215 preferably midwaybetween the outer faces of the finished wall.

With the footing thus formed having the elements 19, Se and el in properlocation, the collapsible core forms, tubes with their reinforcement andin end abutting relationship with the core forms, and the spaced wallmaterial confining forms may be placed, either progressively ascementitious material l2 is poured between the wall forms and extendingexteriorly of the core forms and tubes, or the collapsible core formsand tubes in the relationship described, as well as the spaced wallmaterial confining forms may all be placed for the formation of theentire height of wall before pouring of the cementitious material. Afterthe latter has set, the collapsible The open ends of the core forms 83are removed, with a resulting wall having the characteristics such asmay be 0bserved in Figs. 5, 6 and 7.

It will be noted that, by this method, while the collapsible core formsare removed and hence form no part of the finished wall, the guide stubs8| used in retaining these collapsible cores in place while the mass ofcementitious material is being poured and until it has set, remainembedded in the footing and wall and subsequently serve to assist inanchoring the wall to the previously formed footing and particularlyagainst lateral movement of the wall with respect to the footing. Thisanchoring of the wall to the footing by the guide stubs 8l takes placeadjacent the vertical voids 63, at zones of the wall where the crosssectional area of cementitious material is less than at zones of thewall where the horizontal voids 64 are located. However the wall isanchored to the footing at the last mentioned zones by the reinforcinganchors all, associated with the tubes 215.

I claim:

In the method of constructing a poured concrete wall having a footing,and horizontal and vertical communicating voids, those steps whichconsist of forming a footing having embedded therein upwardly projectingform anchor members spac-ed apart from one another longitudinally of thefooting along lines adjacent its inner and outer sides, upwardlyprojecting guide stubs disposed in groups spaced apart longitudinally ofthe footing, each group comprising a plurality of stubs in linesinwardly of the said lines of anchor members, and upwardly projectingreinforcing anchors disposed in groups between said groups of guidestubs each group of reinforcing anchors comprising a plurality i anchorsin lines inwardly of the said lines of guide stubs; setting in placebetween the stubs of each of said groups of guide stubs, a removablevertically disposed core form for forming a vertical void in the wall;securing to the anchors -ofeach of said groups of reinforcing anchors,apparatus for forming horizontal voids in the wall, including tubes inendwise abutting relation with said removable core forms; detachablysecuring spaced wall material conning forms to said form anchor members;lling the spacebetween said wall material forms, cores and tubesupwardly from said footing with concrete, embedding said guide stubs andreinforcing anchors in the mass of concrete; and, removing said coreforms after the concrete has set so as to open the ends of said tubes tothe vertical voids formed by said core formsand leave the wall tied tothe footing at the zones of the vertical voids by said guide stubs.
